LOOK FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Pa tent no. 263,684, datedSeptember 5, 1882.

Application filed March 20, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. OILLEY, a citizen of the United States,residing at Norwich, in the county of New London and State ofConnecticut, have invented a new and useful Lock for Fire-Arms,-of whichthe following is a specification.

My invention relates to that class of firearms known as double-actingrevolvers, in which the hammer may be drawn back to full-- cock by theuse of the trigger alone, although it cannot be set at full-cock by thismeans, and in which one spring serves to operate the hammer, thetrigger, and the revolver-lever, the object being to improve thearrangement of the sickle-lever, in connection with the hammer, and toso combine the sear with the hammer and the trigger that it (the sear)will be held, back by an 'improved'device While the hammer is making itsstroke. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a longitudinal view, part inelevation and part in section. I Fig. 2 is a detail? in elevationshowing the moving parts at halfcock. Fig.3 is a detail in elevationshowing.

the moving parts at whole-cock. Fig. 4 is a horizontal section on linea: a: of Fig. 1. Fig. 5 is a plan of the sickle-lever detached. Fig. 6is an elevation of the revolver-lever; Fig. 7 is a side elevation of thesame, looking from the back.

The revolver-chamber B, its stop M M, and the ratchet B, not being new,need not be de-' scribed. I

(l is the hammer, swinging about the pivot C. One side of the lower partof this hammer is recessed, as-shown at the depth of the recess beingjust sufficient to receive the sicklelcver D, (see Fig. 4,) saidsickle-lever being pivoted to the hammer O at the point D, and connectedto the spring E by the link D I obtain a double joint or hearing for thesickle-lever D by forming it with a projection,

Di, and by connecting it to t l=.\ 'annner by a pin, D. By thisarrangementofl passing the pin D through the lever proper and through aportion of the hammer '0' and then through the projection D I obtain adouble bearing 0 for the sickle-lever to swing upon which will insureits movement in a true plane, and thus prevent it from being twisted outof its position by the strain transmitted to it through the link 1) bythe spring E.

Instead of making a kert' in the lower part 0f the hammer C for theprojection I), as shown in Fig. 5, a recess may be made on the rear sideof the hammer to receive the part D The spring E, acting through thelink 1) and lever D, serves to operate the hammer C. It also, throughthe same means, operates the revolver-lever F, and as the revolvenleverF is pivoted at F to the trigger K it also operates the trigger. Thetension of the spring E may be adjusted by the screw E. 6

To lessen the friction of the end l) of the lever D in its action on thelever F, I insert a friction-roll at F, which is connected to the leverF by a pin orstud passing through it.

L L L is a pawl-lever or sear for holding the hammer at half-cock, asshown at Fig. 2.

L is a piston-spring, which acts upon the? sear L L L and throws it intothe position shown in Fig. 2 and there holds it until the movement ofthe hammer to full-cock throws it out.

My means for holding the sear L L L" away from the hammer-that is, thepart extending from the half-cock notchc to the point c -is made in theform of a cam, so that in drawing the hammer back to full-cock, as shownin Fig. 3, the part c on the hammer coming in contact with the part L onthe sear depresses it, as shown at Fig.3. Now, when the triggerK ispulled for firing the cusp-point K of the trig- 'ger will come incontact with the point- L of the scar and there hold it until the hammerhas made its blow. Then as the trigger is allowed to retreat the sear isthrown back again by the action of the piston-spring L and is ready toreceive and hold the hammer at halfcock. The action of the trigger whenpulled back upon the sear L L L is to bring the part K"against theforward end of the scar, and thus by mere frictional contact hold itfrom. moving in any direction. No part of the trigger comes in lateralcontact with, the sear, so that the trigger does not under anycircumstances move the sear. Itsonly action on it is to hold it for aninstant during the striking; I00 movement of the hammer, so that itspoint Tl." cannot engage with the notch c on the hammer.

' 5 the hammer O.

The device for holding the hammer at fullcock is not new, and consistsin providingthe upper end of the trigger K with a notch, k,

double joint is made between the hammer and ople'riltingtogether-substantially as described, and for the pnrpose set forth,

2.41116 hafniln'er.v 0, having a cam, c a, the seabl'eior L L If, andspring L, with the triggar K,,having aearved portion terminating in ecusp-point, K, whereby the sear-lever is held down by friction caused byend pressure substantially as described, and for the purpose set forth.
